Despite Statistics being the traditional field for data analysis, people with formal statistical training form a relatively small segment of the Data Science community. Indeed, it is easy to conclude that the influence of Statistics on the field is waning: for instance, Python is slightly more (...)

Abstract: There is a striking connection between the zeroes of the Riemann zeta-function and the distribution of the primes. In this talk I shall mention some analytic properties of the zeta-function that when known explicitly enable one to estimate, very accurately, the size of the n-th prime (...)

Graphs (also called networks) with a high degree of symmetry are particularly nice objects to study mathematically. When studying the symmetries of a graph it is often useful to look at the local symmetries, that is, those that fix a particular vertex.  An important question then becomes whether (...)

Abstract: Maximal intransitive and (...)

The fractional Laplacian is a nonlocal operator naturally arising in several branches of pure and applied mathematics. It presents intriguing features and possesses a great flexibility to a number of applications in physics, biology, numerics and finance. After briefly discussing the basics of this (...)
